The following behaviour differences must be observed when the bidirectional reset is active:
Bit BDRSTEN in register SYSCON cannot be changed after EINIT.
After a reset bit BDRSTEN is cleared.
Bit WDTR will always be ’0’, even after a watchdog timer reset.
The PORT0 configuration is treated like on a hardware reset. Especially the bootstrap loader
may be activated when P0L.4 is low.
Pin RSTIN may only be connected to external reset devices with an open drain output driver.

Function
Internal Reset Indication Output. This pin is set to a low level
when the part is executing either a hardware-, a software- or a
watchdog timer reset. RSTOUT remains low until the EINIT
(end of initialization) instruction is executed.
Non-Maskable Interrupt Input. A high to low transition at this
pin causes the CPU to vector to the NMI trap routine. When
the PWRDN (power down) instruction is executed, the NMI pin
must be low in order to force the C164CI to go into power
down mode. If NMI is high, when PWRDN is executed, the
part will continue to run in normal mode.
If not used, pin NMI should be pulled high externally.
Port 8 is a 4-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state.
The following Port 8 pins also serve for alternate functions:
